JPG to PNG Converter

How to Convert JPG to PNG Online

1. Upload Your JPG File: Drag and drop or click "Add Files" to select JPG, JPEG, or JFIF files. Photos, screenshots, scans, and exported assets all work. Batch is supported — drop in an entire folder.
2. Pick a Compression Level (Optional): PNG always uses lossless compression. Choose a compression level (Highest → Lowest) to trade encoding speed against file size. "Highest" produces the smallest PNG but takes longer; "Lowest" is fast and slightly larger.
3. Resize and Set DPI (Optional): Pick a resolution preset, scale by percentage, or set custom width × height. Set DPI from 72 / 96 (screen) up to 300 / 600 / 1200 (print). Bit depth and color palette size (2 / 4 / 8 / 16 / 32 / 64 / 128 / 256 colors) let you create indexed-color PNGs for very small file sizes.
4. Convert and Download: Click Convert. Files convert on our servers and download individually or as a ZIP — no sign-up, no watermark.

Why Convert JPG to PNG?

JPG (or JPEG) is the dominant format for photographs because it compresses smoothly via discrete cosine transform — small files, good for storage and sharing. PNG is lossless: every pixel is preserved exactly. Common reasons people convert JPG → PNG:

• Stop the re-save quality decay — Every time a JPG is edited and re-saved, it re-encodes and loses a little more quality. Converting to PNG before editing freezes the image at its current quality. Edit and re-save endlessly without further loss.
• Adding transparency — PNG supports an alpha channel; JPG doesn't. Designers convert to PNG when they need to overlay an image on another design, knock out a background, or create a logo with a transparent background.
• Sharp text, line art, screenshots — JPG creates visible "ringing" and "mosquito noise" around high-contrast edges (text, UI elements, vector lines). PNG preserves them cleanly. If a JPG screenshot or diagram looks fuzzy, convert to PNG to stabilize it before further editing.
• Print and archival quality — PNG at 300+ DPI is the safe choice for printable assets and lossless archives. JPG for the same content visibly degrades at 300% zoom.
• Inputs to AI / OCR / image-processing pipelines — Many image-recognition models train on PNG-style lossless data. Converting JPG → PNG before feeding produces fewer compression-artifact false positives.
• Replacing a corrupted or legacy JPG — A clean PNG remaster preserves whatever's left of the JPG's quality and won't degrade further.

Frequently Asked Questions

Does converting JPG to PNG improve quality?

No — it cannot restore detail that JPG compression already discarded. The PNG output is a faithful copy of whatever the JPG decoded to, including any compression artifacts (blocking, ringing, mosquito noise) baked into the source. The benefit is preventing future quality loss when editing and re-saving, plus gaining transparency support.

Will the PNG be larger than the JPG?

Yes — typically 3-5× larger for photographic content. A 500 KB JPG often becomes a 1.5-3 MB PNG. For images with flat color, screenshots, line art, and limited palettes, PNG can actually be smaller than JPG. Use the indexed-color palette options (8 / 16 / 64 / 256 colors) to dramatically shrink PNGs of graphics and icons.

How do I add transparency after converting?

Conversion alone doesn't add transparency — JPG has none to preserve. After converting, use JPG to PNG with transparency workflows in an image editor (Photoshop, GIMP, Photopea) to remove a background and re-save. The PNG container can then carry the alpha channel.

What DPI should I pick?

72 or 96 DPI for screen-only use (web, social, presentations). 150 DPI for inkjet draft prints. 300 DPI for high-quality prints, magazines, and brochures. 600+ DPI for fine-art prints and large-format work. Note that resampling up doesn't add real detail — the highest DPI worth setting is whatever matches the source resolution.

Can I batch convert hundreds of JPGs at once?

Yes — drop in entire photo folders, screenshot archives, or asset libraries. Each file converts in parallel withon our servers and downloads individually or as a single ZIP. Settings can apply uniformly or be set per-file.

Will my EXIF metadata (date, camera, GPS) survive?

Yes by default — EXIF is preserved in the PNG output (PNG stores EXIF in tEXt or eXIf chunks). If you want to strip metadata for privacy, look for "remove EXIF" in the advanced options.

What's the difference between JPG, JPEG, and JFIF?

All three are the same format. JPG and JPEG are interchangeable file extensions for the JPEG image standard. JFIF is the most common file-format wrapper used in practice — almost every "JPG" you see is technically a JFIF. XConvert handles all three identically.

Should I use 8-bit or 16-bit per channel PNG?

8-bit per channel (24-bit RGB or 32-bit RGBA) is standard for almost everything — web, print, design. 16-bit per channel matters for HDR work, scientific imaging, and editing pipelines that need extra dynamic range. Most PNG viewers display 16-bit PNGs but downconvert to 8-bit on screen.

Can I convert PNG back to JPG?

Yes — see PNG to JPG for the reverse direction (useful when you need a smaller file for email or web).
